Dell Magazine’sDiabolical Digits (Millennium Media Group) is, indeed, diabolical. Once you figure out how to play – it can take a while even with text and audio Help – you probably won’t be able to stop. It is very snappily rendered, with 3D graphics that put a new spin on puzzle solving. Designed by Pierre Berloquin, notorious puzzle master, this program could clearly drive a person crazy. If puzzles are your thing, Diabolocal Digits is a honey of a game.
